Ancor 6 AWG Single Conductor Wire - Per Foot

Marine Grade Wire Built for the Harshest Conditions

Ancor 6 AWG single conductor wire is purpose-built for the demanding marine environment. Whether you're rewiring a panel feeder, adding a high-draw circuit, or replacing aging conductors, this wire delivers the reliability that Canadian boaters depend on. With a 120-amp ampacity rating outside engine spaces (102 amps inside), 6 AWG is a workhorse gauge suitable for windlasses, inverters, high-output charging systems, and other substantial loads.

Every foot of this wire is constructed with tinned copper stranding that guards against the corrosion and electrolysis that bare copper simply cannot withstand in a saltwater environment. The premium vinyl insulation resists salt water, battery acid, oil, gasoline, heat, abrasion, and ultraviolet radiation — all common threats aboard any vessel.

Ultra-Flexible Tinned Copper Construction

Ancor uses Type 3 ultra-flexible stranding composed of 266 strands of 30 AWG tinned copper, giving this 6 AWG wire a circular mil area of 26,600. That fine stranding makes the wire noticeably easier to route through tight spaces, around corners, and into terminal connections compared to stiff, coarsely stranded alternatives. It also resists fatigue caused by engine vibration and the constant flexing that occurs aboard a moving vessel.

Insulation That Performs in Extremes

The exclusive vinyl insulation carries a 600-volt rating and is temperature-rated at 105°C dry and 75°C wet. For Canadian boaters who face frigid shoulder seasons and harsh winters, the wire remains flexible down to -40°C — the same temperature where Fahrenheit and Celsius converge. This means you can confidently install or service wiring in cold weather without the insulation cracking or becoming brittle.

Exceeds Key Marine Electrical Standards

Ancor Marine Grade wire products exceed UL 1426, ABYC, and US Coast Guard Charter Boat (CFR Title 46) standards. These aren't automotive-grade conductors repurposed for boats — they are engineered specifically for the corrosive, high-vibration marine environment. Using properly rated marine grade wire is essential for safety and for meeting the requirements of marine surveyors and insurance underwriters.

Sizing Your Wire Run Correctly

Choosing the correct wire gauge involves more than just matching ampacity to the load. Voltage drop over the length of the run is the controlling factor in low-voltage DC systems. ABYC recommends a maximum 3% voltage drop for critical circuits such as bilge pumps, navigation lights, and electronics, and 10% for non-critical circuits like cabin lights.

For a 6 AWG conductor at 12 volts with a 3% voltage drop allowance, Ancor's tables show this gauge is appropriate for runs carrying up to 30 amps at lengths up to 30 feet (total positive and negative run combined), or lower amperages at longer distances. Always consult the Ancor Wire & Technical Data catalogue — linked on the product page — to verify the correct gauge for your specific circuit.

Available Colours and Buy-by-the-Foot Convenience

This wire is available in three colours — red, black, and yellow — allowing you to follow ABYC recommended colour coding for DC positive, DC negative, and other designated circuits. Sold per foot, you can order precisely the length you need without committing to a full spool. Simply enter the number of feet required in the quantity field at checkout.
